1. What are the methods for activating lithium-ion batteries for vehicles?
1. Concatenation method. Another normal voltage 12 volt battery is connected in series to the entire battery. For example, if the original car was a 48v20ah battery, we would connect another 12v20ah battery in series. A fully charged 12V battery has about 13V. After connecting in series, the voltage of the entire battery can be increased and then charged with the original charger. When the charger is plugged in, it will turn red. At this point, you can charge. When the charger turns green, remove the other series batteries. Then charge normally
2. Parallel method. For example, the original 48v20ah batteries were connected in parallel. For a 48v20ah battery, the high voltage terminal will flow into the low voltage terminal. This method is also used by many electric vehicle Li-ion battery dealers to detect dead batteries, which can also be recharged
3 Low-voltage charging method. Choose a small charger to charge. For example, if using a 48v20ah charger to charge a 60v20ah battery. Under normal circumstances, you can charge the lithium-ion battery of this group of electric vehicles with a small charger first, and then replace the original charger to continue charging. For example, if the rechargeable Li-Ion battery is 60V, it can be charged first with a 48V charger and then with a 60V charger. This operation can also activate the lithium-ion battery of the electric vehicle at a certain rate (2) Find a set of lithium-ion batteries of the same model as the main battery and connect it in parallel with a set of rechargeable lithium-ion batteries of the electric vehicle. Discharge a good battery to a rechargeable battery. After several parallel charging cycles, you can also reactivate the electric vehicle's lithium-ion battery (3) to try a quick charge for one to two hours, and use a professional instrument to detect if the voltage rises. If the charge rises, you can choose to continue charging with the original charger, which allows you to activate the EV's lithium-ion battery. If the lithium-ion battery of an electric vehicle is severely de-energized and cannot be activated, the only option is to replace it with a new one
